vOriginal application led October 8 0, 1923, Serial No. 671,631. Divided and this application fled i December 15, 1925. Serial 11o-75,514.

The invention relates to equipment on a typewriting machine for expedltlng the manipulation therein of work-pieces, such for instance as bill-sheets.` Such equipment I involves not only a magazine or Vcontainer from which blank statement or bill sheets may be successively ,passed to the platen; but also means for facilitating quick placement and fixing of the bills in-typlng pos1- l0 tion, and removal thereof from the machine; and preferably means whereby to employ a record-sheet upon which to make the entries, made upon the successive bill-sheets,

simultaneously with the typing on the latter. l5 The invention, as to certain features thereof, also 'relates to means for gaging the position of the work-pieces on the platen.

Heretofore, the magazine or container for the bill-sheets has been out of the body of the machine, in a more or less inconvenient position; or, when in the machine, has. been of a kind` from which automatic feed of the bill-sheets therefrom, to the platen, has been attepted.

A feature of the present invention is a mounting ofthe magazine, directly upon the platen-carriage; and whence, .regardless pf the position of the carriage, the billsheets may 'be passed by hand, from the magazine, directly down the front of the platen to typing position.

Another feature ofthe invention is a style and setting of magazine, such that the blank work-pieces therein offer themselves separately toA the operators fingers; and such that, upon lacement of a pack` of Work-pieces therein, the latter are caused automaticall to step themselves off one from the `ot er so that only one at a time will present itself to the operators fingers.

Still another feature'of the invention i" the provision of means, preferably intelposing 'itself in the path of -movement of the operators fingers, whereby, upon insertion of the work-pieces, the same are gaged in correct position for commencement of t ing.r

T y1s application is a division of my application filed October 30, 1923, Serial No. 50v 671,631.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Y

Figure l is a view, -in end elevation, partly cross-sectional, of the carria and associate parts of a typewriting mac ine embodying the present mvention.

Figure 2 is a front view of the apparatus shown in Figure 1.

A platen 10, by means of an axle 11,' is journaled in the side pieces 12 of the latenframe. This frame is'shiftable up an down between case-positions by any suitable mechanism, not shown, For su porting the platen-frame and assisting in t e case-shift .of the latter, pins 13 on the side plates of the platen-frame are set upon arms 14 fast to a rock-shaft 15, u on which shaft is a spring, not shown, ten in'g -to lift the platenframe. The .case-shifting mechanism may be that shownin the standard Underwood typewriting machine.

The platen-frame is also provided with a paper-shelf 16, which forms an extension of the usual rear paper-table 17 and a ronextension 18, for guiding work-pieces own behind the platen and around' under the same' to the printing line of the front there-l of. The usual front and rear feed-rollers 19 and 20, respectively, are also provided. The front rolls 19 are on a shaft 21, seated on the arms 22 of bell-crank levers pivotally mounted on a shaft 23, secured to the end plates 12 of the, platen-frame. The rear feed-rolls 2O are on a shaft 24, seated on the arms 25 of bell-cranklevers also pivotall mounted on the shaft 23. The bell-cra levers which comprise the arms 22 have other arms 26 which depend to the rear of a shaft 27; and the bell-crank levers which;

comprise the arms 25 have other arms 28 whlch depend tothe front of the shaft 27. Leaf-springs 29, bearing upon the arms 22 -and 25, tend to rockithe arms upward to throw the feed-rolls against the platen, and

therefore tend .to press the arms 26 and28 against the shaft v27. Ihe shaft 27 has Hats 30 cut therein vwhere the arms 26 and "-28 engage the same; When the feed-rolls are ineffective position, the arms 26 and 28 bear against the Hats 30. When, however, the shaft 27 is rotated,the arms 26 and 28 are forced apart to drawn-If:y down thefeedrolls. The shaft 27 is joiiiale'd in th'e'gf-,sde plates A12 of the platen-frame. roll mechanism, just described, is that found irlthe standard Underwood typewriting mac me.

The vfeedlos d pieces 57 ,supported on a shaft been Jfed down the table 16 For throwing1 od the feed-rolls, the {tollowing device is einployed'. Fast to'the shaft 27 is an arm 31, which is connected at one end to a link 32; the other end oil the link 82 being connected to a bell-crank lever 88 on a stub-shaft 84, mounted in the righthand side plate of the platen-frame. @ne arm 85 of this bell-crank lever connects with a link 86, which extends nects at 87 to one arm 38 of a bell-crank lever iixed to a rock-shaft 89. 'llhe rockshaft 39, at its right-hand end, has bearing .in a bracket 40 secured to the right-lian side piece 41 of: the carriage. rll`he letthand end of the rock-shalt 39 is journaled in a bracket 42, which extends forward and is connected to 'the Afront rail 43 of the carriage. rlhe bell-crank lever, of which the arm 38 forms a part, also has a torwaidly-extending arm 44 which supports the right-hand end of a bar 45. rvthe left-hand bar 45 is supported by an arm Jforward and conend of this 46, also made tast to the rock-shalt 89. lressure on bar 45, as by the palm, at any point of the bar, results in movement oit the bar from the dotted-line Figure 1 position to the full-line Figure 1 position, thereby releasing the feed-rolls. A lip 47, oilset from the lower edge of the bar-supporting arm 44, by engagement with the carriage side piece 41 determines the downward movement, and roll-releasing position, oil' the bar 45.

rl`he carriage has movement, in the usual manner, in letter-feed and Ireturn directions, on the main iframe 48 oit the machine.

At its rear, the carriage rides upon a rail 49 on the main frame, and, at its front, the carriage is provided with a. roll 50, which travels on a runway 51 on the main frame. i

ln the drawings, a record-sheet 52, laced by a carbon-sheet 53, `is shown as having and around the platen, and as having .the typed portion thereof extending rearward over the top oit the platen. The carbon-sheet is shown as having its leadin end turnedg at 54, over the, leading end ot the record-sheet, so that the two sheets may be fed into the machine and around the platen as a unit, without slipping of one on the other. The recordsheet, as hereinafter explained, is to receive the entries made successively upon a seriesof individual statements; and, in order that the record-sheet may be held in place upon the platen while the feed-rolls are released for the insertion and removal of the individual statements, a pair of clips are provided. 'lhese clips are shown as consisting of spring-fingers 55, carrying rollers 56,

which are adapted to bear upon the recordsheet on the platen.

The spring-fingers 554 are 'secured to U- Leraars The shaft 58, in turn, is supported bpb ilar ttl-shaped pieces 59, secured to locks 60 on the side plates 61 ot a 'trame which is set upon and detachably secured to the flanges 62 on they side pieces 12 o the platen-trame. 'lhe shaft 58 is revolnble in the brackets 59, but is held against accidental rotation by means of rollers 68 on the brackets 59, which set into a slot` 64 extending longitudinally the full length or the shatt 58. Leaf-springs' 65 on the brackets 59 hold the rolls 68 in the slot 64, but yield to permit the rolls 68' to cam themselves out of the slot or brackets 57, which support the paperclips 55, are held against angular displacement on the shalt 58 by means of rolls 66, similar to the rolls 63, and which are held in the slot 64 by leaf-springs 67, similar to the springs 65. llhen pressure is applied to the clips 55 to throw the same up to release the record-sheet, the springs 67 yield to permit the rolls 66 to release themselves from the slot 64 in the shaft 58a ".llhe detachable trame. which supports the shaft 58 is secured to the platen-traine by thumbscrews 68, which pass through the blocks 60 and side pieces 6l or" the detachable traine, and which screw into the dangers 62 on the side pieces 12 ot the platen-trame.

rlhe shaft 58 also serves as a support 'for the container or magazine 7 0 `for the blank statement-sheets or bill-heads 71. This container (see Figure 2) has a rear wall 72, a front wall 78, and side walls 7 4,. riilhe front wall 78, toward the base thereof, is tapered downward and rearward, at 7 5, to the rear wall 72, so that the statementsheets 71, from rearto liront, protrude each slightly above the sheet next rearward ci the same; thereby enabling the operator with his lingers, always 4to seize one sheet, and not more, at a time.

For supporting the magazine on the shaft 58, there is riveted to the rear wall ot the magazine a air ot brackets 76. These brackets, below t e lower edge of the niagazine,are odset, at 77, rearward for attachment each to a ll-shaped bracket 78, similar to the brackets 57 and 59. .'lhese brackets 7 8 are connected to the shaft 58 by rollers 79, set in the slot 64 in therein by springs 80, inthe same manner as the rollers 63 and 66. Although this forni of attachment of the container to the shaft 58 permits angular movement oit the the shalt, and held slot 64 obviouslyl 64, lor rotation 4 of the shaft 58 when desired. The lll-pieces against accidental rightward or leftward displacement. It follows, therefore, that the ma ezine is placeable and detachable as a unlt with 'the rame'which carries the shaft 58 and pa r-clips 55; so that, when means of the usual line-space mechanism, of

which only a ratchet-wheel 82 on the platenaxle is shown.' The paper-finger rollers 56, if not previously applied, are then applied to the record-sheetu The operator then removes the front statement-sheet from vthe magasine 7() and passes the same down in front of the platen, in front of the carbonsheet. As'the operators hand moves downward, the operators palm strikes the bar 45 at some point thereof, and throws off the feed-rolls, rmitting the lower edge of the statement-s eet to be passed-around the platen between the latter andthe apron 18.

The correct position for typing lon the tir-st line on the statement-sheet is determined by registration of the upper edge of the statement-sheet with the upper edge of a age-bar 83. This bar 83 is secured at its en to arms or brackets 84, in turn, secured to U-sha ed pieces or brackets 85, similar to the brac lets 59 and 78, and similarly con-- nected to the shaft 58 by means'of rollers 86, held by leaf-s rings 87 in the slot 64 in the shaft, The eft-hand bracket 84 also carries a side-marginal gage for the statement-sheet. This gage is shown as comprising a plate 89, havin a iange 90 oifset therefrom, against vw ich flange the lefthand marginsl of the statement-sheets may be set. To permit of adjustment' of the margmal gage, the same is slottedat 91, longitudinally ofthe plate 89.; and screws 92,

which secure the gage-plate 89 to the bracket 84, pass through the slot 91. ,When the screws aretightened, the marginal gage is held in adjusted position.'

Upon registration of the upper edge of the statement-sheet with the upper edge of the gage-bar 83, the operatorshand is lifted to release the bar 45 and to permit the springs 29 to throw the pressure-rolls to prosltion or holding the statement-sheet. If typing at' the rst position on the statement'- s eet is not desired, and typing is desired at some other position on the statementsheet, the usual wing-scales, not shown, may be used insteadof thegage-bar 83, as the means tor gaging the position of the statement-sheet. The statement-sheet n may be held up against the platen, above the printing line, by means of the usual movable paper-holding fingeror guard, which is not shown, Vbut which is pivotally connected to the front rail of the carriage, and vis found in standard Underwood typcwriting machines, After typing on a statement-sheet is completed, the carriage is thrown rightward for commencement of writing on another statement-sheet. Thelever by which the'carriage is thus returned, ordinarily effects a single line-space movement of the platen by mechanism not here shown. This results in a line-space movement of the record-sheet 52 and carbon 53 so as to prepare the same` for receiving the entries to be made upon the next succeeding statement-sheet. The paper finger or guard, last mentioned, is thereupon thrown out, and the statementsheet, which has been typed, pulled forward as indicated in Figure 1. Thereupon', the operator removes from the magazine the front statement-sheet therein, and passes the same down between the platen and the statement-sheet last typed. In so doing, the operators hand depresses the bar 45 to release the feed-rolls, so that the `statementsheet, then being introduced, may be passed around the' platen between the feed-rolls andthe platen; In this operation, the previously-typed statement-sheet serves to guide the next statement-sheet around the platen between the front edge of the apron 18 and the laten. While the newly-inserted statemen -sheet is'held with its upper edge aligned with the upper edge ofthe gage-bar 83, the operator, with his other hand, then removes the previously-typed statement-sheet. This done, the operator removes his hand from the bar 45 and from the newly-inserted statement-sheet. All is now ready for t ping on lthe statement-sheet then in the mac me.

It willbe noted upon reference to Fi re 2 that the ypaper-linger rolls 56do not ar upon the'carbon-sheet: they bear upon the record-sheet outside of the side boundaries of the carbon-sheet. For holding the carbon-sheet against forward displacement or crumpling durin the removal of a typed statement, paperngers are not necessary in the present case; because, as hereinbefore stated, the fresh statement-sheet is inserted between the platen and the typed statementsheet before the latter is removed. The fresh statement-sheet, therefore, prevents frictional engagement of the typed statement-sheet with .the carbon-sheet as the typed statement-sheet is pulledout. On removal of the' ty ed' statement-sheet, the same therefore sli es over the outer face of the inserted fresh' statement-sheet, without dragging on the carbon. The carbon-sheet is also held against backward displacement around the platen, yvithout direct applicaion,

tion of any paper-fingers thereto. This is because the paper-finger rolls bear upon the record-sheet `to hold the latter against backward displacement; and the leading end of the carbon-sheet being looped over the leading end of the record-sheet, the record-sheet holds the carbon-sheet against backward displacement. The statement-sheet upon being inserted, therefore, instead of disturb-` ing the carbon-sheet, only tends to smooth the same out on the platen.V

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim:
